ODOT-DPM01 Modbus RTU to Profibus-DP with 1 port RS485 & 1 port Profibus-DP (aluminum alloy casing)

PROFIBUS (Process Field Bus) is a standard for fieldbus communication in automation technology and was first promoted (1989) by BMBF (German department of education and research). It is the world’s most successful fieldbus, with more than 31 million devices installed by the end of 2009. Over 5.4 million of these were in the process industries.

There are two variations of PROFIBUS in use today. The most commonly used PROFIBUS DP, and the lesser used PROFIBUS PA.

PROFIBUS DP (Decentralized Peripherals) – It is used to operate sensors and actuators via a centralized controller in production (factory) automation applications.

PROFIBUS PA (Process Automation) – It is used to monitor measuring equipment via a process control system in process automation applications. This variant is designed for use in explosion/hazardous areas.

The ODOT-DPM01 gateway is a Modbus-RTU/ASCII to PROFIBUS-DP protocol converter. This ODOT-DPM01 connect Modbus device to Siemens PLC(S7-300/1200/1500/400) with PROFIBUS-DP communication interface or DCS system with DP master. It adopts aluminum alloy shell with firm design and supports DIN-rail installation. All serial signal provides built-in photoelectric isolation.
